Suitable for my 2 year old daughter who has a size of 18 months. But for now you push and she keeps her feet on the pedals as it records the movement must be his legs. Very good article of good quality. We verons to use resistance when mistinguette will use it alone. I recommend this article to all as the first tricycle for children because in addition there is the high back belt and therefore no risk of falling or slipping. So the pedals are well slip the child keeps feet above.
